Description
0
The run command in any mode other than drive mode is disabled. (The Inverter will start
operating with the run command input again in drive mode.)
1
A run command is enabled. (The Inverter will start operating according to the present run
command in drive mode or any other mode.)
Note The run command is disabled if the Digital Operator is specified with parameter b1-02
set to 0.
Note If the parameter b1-08 is set to 1, the Inverter will start operating regardless of whether parame-
ters are adjusted in program mode or not. Take necessary safety measures to prevent accidents.
H
Setting DC Injection Braking (b2-01 to 04)
The DC injection braking function decelerates by applying a DC magnetic field to the motor.
DC injection braking time at start:
This is effective for temporarily stopping and then restarting, without regenerative processing, a mo-
tor coasting by inertia.
DC injection braking time at stop:
When there is a large load, this is used to prevent coasting by inertia when the motor is not complete-
ly stopped by normal deceleration. The stopping time can be shortened by lengthening the DC injec-
tion braking time or increasing the DC injection braking current.

•
For the excitation level (b2-01), set the frequency for beginning DC injection braking at the time of
deceleration. If the excitation level is lower than the minimum output frequency (E1-09), the DC injec-
tion braking will begin from the minimum output frequency.
Note 1. In flux vector control mode, DC injection braking becomes the initial excitation starting fre-
quency at the time of deceleration. In that case, braking starts from the excitation level regard-
less of the minimum output frequency setting.
Note 2. The excitation level is also used as the operating frequency for the zero servo function (for flux
vector control only).
